BACKGROUND OF THE INVENTION

Traditionally, a parts salesperson must carry with him or her all of the sales tools related to the particular kinds of parts that they wish to sell. These tools include parts catalogs, sample parts, and parts order forms. To carry the combination of all of these sales tools can be very cumbersome for a salesperson. For a salesperson to bring all of these sales tools into a customer visit could be quite difficult. In particular, if a parts salesperson must bring in parts catalogs for several types of parts as well as several different manufacturers of parts, and in addition the corresponding samples of each type of part by each of the manufacturers, the salesperson may find this overwhelming and choose to limit the number of parts that they sell or the particular manufacturers that they sell for.

Further, looking up a part number in a catalog can take significant amounts of time. In addition, trying to match a particular part with a particular need can be very difficult. For instance, trying to find a particular filter which will fit on a particular product may be impossible to accomplish in a limited amount of time. It can be even more difficult to determine all parts that a user with many types and brands of equipment may require. Further, the generation of a corresponding proposal or order, particularly a personalized one, has been difficult. An additional long felt need has been the need to educate sales people with respect to a particular product line of a manufacturer as well as the features and benefits of those particular products in comparison to other comparable products in a relatively quick and efficient manner.

The preferred system seeks to overcome these problems by linking these and other functions into a single system.

SUMMARY OF THE INVENTION

A computerized system is provided for providing a salesperson with assistance related to training and sales of parts corresponding to particular products. More particularly, a computerized system incorporating a data storage device, a display apparatus, a part selection device and a user interface mechanism is provided to enhance the efforts of a parts salesman. The data storage device electronically stores graphic and textual parts-related information including specifications, features and customer benefits. The display apparatus electronically displays portions of the graphic and textual information in order to provide training and sales assistance related to part features and customer benefits. The part selection device electronically selects a particular part by navigating through part choices menus based on stored part specifications. The user interface means controls the operation of the display apparatus and the part selection device parts so that each of the respective parts are operatively coupled and related to one another.

The following is a description of a preferred embodiment computerized system for providing a salesperson with assistance related to training and sales of parts corresponding to particular products. The system as generally described in FIGS. 1, 1A, 1B, 1C and 1D will further be detailed in the following preferred embodiment discussion. In the preferred embodiment discussion that follows, the user may select from several generic types of parts to look up a particular part under a cross-referencing/parts selection procedure. In the preferred embodiment, the types of parts under the cross-referencing/parts selection procedure include batteries, filters, remanufactured electric parts, lubrication and bearings.

Referring now more particularly to the preferred battery cross-referencing section as depicted in FIGS. 2, 3A, 3B, 4, 5 and 6, a user may choose a battery by specifying a part number, equipment application or battery specifications. More particularly, FIG. 2 is a flow chart diagramming a preferred procedure for selecting a battery by a part number. Upon selecting the choice of specifying a battery by part number 200, a user is prompted to enter a part number 202. Subsequently, part selection device 106 will check if the part number is valid 204. If the part number is not valid, part selection device 106 will prompt the user to enter a part number 202. Otherwise, if the part number is valid, the part selection device 106 will display particular part information 206 and select that particular part 208. To select that particular part 208, part selection device 106 accesses the battery information 300 stored in data storage device 104 and shown in FIG. 6 to choose a particular part 250. By using the cross-reference file 294 in conjunction with the part number, a particular set of information is retrieved from battery information 300. Subsequently, the part selection device 106 ends the procedure get part by part number for battery 210.

Alternatively, a user may choose to pick a particular battery by specifying a particular equipment application for the battery. In choosing the particular equipment application, part selection device 106 preferably will go through a set of steps as depicted in the flow chart shown in FIGS. 3A and 3B. In choosing to pick a part by equipment application 212, part selection device 106 will retrieve information stored in data storage device 104.

The information stored in data storage device 104 preferably is in a structured form 270 as depicted in FIG. 5. The preferred structured file format 270 for batteries comprises several records including a first and second pointer as well as subobject count information. The records shown are configured in a hierarchical format with seven layers of hierarchy. In the preferred embodiment, on the first level of the hierarchy, are records for info 1 data. Each record for info 1 data includes a pointer 272 to particular information for that particular info 1 data, a pointer 274 to the next record of info 1 data and a count of subobjects 276 for the set records related to that particular info 1 data record. The subsequent record following the first info 1 record in preferably the first subobject related to the first info 1 record or more specifically a record related to info 2 data including a pointer 278 to the info 2 data and a pointer 280 to the next info 2 record also related to that particular info 1 data record which was selected. This hierarchy of records continues further down into the record including a pointer 282 to info 3 data. Similarly, the next record shown includes a pointer 284 to info 4 data, with the next record including a pointer 286 to info 5 data. Furthermore, the next record is shown including a pointer 288 to info 6 data. Finally, the following record preferably includes BCI group and cold cranking amps data 290 for a particular battery, with the next record including BCI group and cold cranking amps data 292 for another battery. It will be appreciated by those skilled in the art that the above discussion was merely a simple example of what a structure form 270 might include. The form 270 might further include more records at each level of the hierarchy to accommodate addition part data in the structured form 270.

Referring now to FIGS. 3A and 3B, after a user chooses to select a particular battery by equipment application 212, preferred part selection device 106 gets and displays section 1 information at 214. This section 1 information may be derived from all records in file format for battery cross-reference 270 which have a pointer 272 to info 1 data. The information may be derived by accessing file 270 and the first record containing a pointer 272 to info 1 data and subsequently accessing each record pointed to by a pointer 274 which points to the next record having a pointer to info 1 data. This process is typically repeated until the pointer which points to the next record having a pointer to info 1 data does not contain a pointer to another record having a pointer to info 1 data.

Subsequently, a user typically selects one of the elements from the section 1 information 216 and the part selection device 106 determines whether other sections are needed to particularly define the equipment application 218. If another section level is not needed to completely define the battery for a particular equipment application, part selection device 106 will display part information 248. Otherwise, part selection device 106 will get and display section 2 information 220 from file 270 records in a similar manner as was used to get and display section 1 information. These records typically include the first record following the info 1 record selected in section 1 choosing step 216, wherein the record following the first record comprises a pointer 278 to info 2 data, and further includes data derived from all records in the sequence of records including the pointer to the next info 2 data record.

Subsequently, a user typically selects one of the elements from the section 2 information 220 and the part selection device 106 checks if other sections are needed to particularly define the equipment application 224. If another section level is not needed to completely define the battery for a particular equipment application, part selection device 106 displays part information 248. Otherwise, part selection device 106 will get and display section 3 information 226 from file 270 records in a similar manner as was used to get and display section 1 information. These records typically include the first record following the info 2 record selected in section 2 choosing step 222, wherein the record following the first record comprises a pointer 282 to info 3 data, and further includes data derived from all records in the sequence of records including the pointer to the next info 3 data record.

Subsequently, a user may select one of the elements from the section 3 information 228 and the part selection device 106 checks if other sections are needed to particularly define the equipment application 230. If another section level is not needed to completely define the battery for a particular equipment application, part selection device 106 displays part information 248. Otherwise, part selection device 106 will get and display section 4 information 232 from file 270 records in a similar manner as was used to get and display section 1 information. These records would include the first record following the info 3 record selected in section 3 choosing step 228 wherein the record following the first record comprises a pointer 284 to info 4 data and would further include data derived from all records in the sequence of records including the pointer to the next info 4 data record.

Subsequently, a user typically selects one of the elements from the section 4 information 234 and the part selection device 106 checks if other sections are needed to particularly define the equipment application 236. If another section level is not needed to completely define the battery for a particular equipment application, part selection device 106 displays part information 248. Otherwise, part selection device 106 will get and display section 5 information 238 from file 270 records in a similar manner as was used to get and display section 1 information. These records would include the first record following the info 4 record selected in section 4 choosing step 234 wherein the record following the first record comprises a pointer 286 to info 5 data and would further include data derived from all records in the sequence of records including the pointer to the next info 5 data record.

Subsequently, a user may select one of the elements from the section 5 information 240 and the part selection device 106 checks if other sections are needed to particularly define the equipment application 242. If another section level is not needed to completely define the battery for a particular equipment application, part selection device 106 displays part information 248. Otherwise, part selection device 106 will get and display section 6 information 244 from file 270 records in a similar manner as was used to get and display section 1 information. These records would include the first record following the info 5 record selected in section 5 choosing step 240 wherein the record following the first record comprises a pointer 288 to info 6 data and would further include data derived from all records in the sequence of records including the pointer to the next info 6 data record.

Subsequently, a user typically selects one of the elements from the section 6 information 246 and part selection device 106 displays part information 248.

After displaying the part information 248, part selection device 106 accesses the battery information 300 stored in data storage device 104 and shown in FIG. 6 to choose a particular part 250. By using the cross-reference file 294 in conjunction with the particular BCI group and designated cold cranking amps for the particular part, a particular set of information is retrieved from battery information 300. Subsequently, the part selection device 106 ends the get part by applications for battery procedure 252.

Alternatively, a user may choose to pick a particular battery by specifying a particular battery description. In specifying the particular battery description, part selection device 106 preferably will go through a set of steps as depicted in the flow chart shown in FIG. 4. In choosing a particular battery by battery description 254, preferred part selection device 106 will retrieve parts-related information by using cross-reference file 294 in combination with battery information 300 depicted in FIG. 6. The cross-reference file 294 and battery information 300 are stored in data storage device 104. The part selection device 106 displays battery description types 256. These description types may include BCI number, cold cranking amps, reserve capacity, voltage, length of battery, width of battery, height of battery, warranty period, and price of the battery. The part selection device 106 prompts a user to choose a description type 258. Upon a user specifying a particular parameter for the battery description 260, the part selection device 106 checks to see if the description is valid 262. If the description is not valid, then the parts selection device 106 returns to prompting the user to choose a description type 258. Otherwise, if the description is valid, the part selection device 106 displays the part information which is defined by the description entered 264. This part information may include more than one part if more than one part meets the constraints entered in the part description 260. A user typically will select as much of the battery description as is needed to specify only a few battery parts. Subsequently, preferred part selection device 106 prompts the user to select a particular part 266 from the displayed part information. Upon selection of the particular part, the part selection device accesses the cross-reference file 294 to retrieve the particular part information from battery information 300.

Referring now more particularly to the filter cross-referencing section as depicted in FIGS. 7, 8A, 8B, 9 and 10, a user may choose a filter by specifying a part number or equipment application. More particularly, FIG. 7 is a flow chart diagramming a preferred procedure for selecting a filter by a part number, and FIG. 10 shows a preferred embodiment file structure containing filter information stored in data storage device 104 for use in selecting a filter by part number. Upon selecting the choice of specifying a filter by part number 302, a user is prompted to enter a part number 304.

Subsequently, part selection device 106 will check if the part number is valid 306. The validity checking is accomplished by finding an HPTR record in the HPTR file 381 which is substantially similar to the part number entered. The HPTR file 381 comprises HPTR records sorted in part number order. Each HPTR record comprises a pointer to a record within an HTAB file 380 comprising a part number. If the part number is not valid, part selection device 106 will prompt the user to enter a part number 304 once again.

Otherwise, if the part number is valid, then part selection device 106 will display manufacturers of the part number 308 and prompt the user to select a manufacturer of the part number. The list of manufacturers displayed is derived from data storage device 104 by accessing the same record number in the DPTR file 383 as was found to be a valid part number in the validity checking. The DPTR file 383 comprises the same number of records as the HPTR file 381 sorted in the same order by part number. Each DPTR record includes a pointer 384 to a manufacturer in a MFGR file 386 and a pointer 385 to an XREF file 389. The XREF file 389 is a file sorted by part number comprising records including a pointer 390 into a record within DPTR file 383, a pointer into INFO file 388, a pointer 394 to another XREF record and the price 396 of the part.

For example, a list of manufacturers is derived by taking HPTR record number (e.g., the record including pointer 382) of the valid part number and using it to access the same record number in the DPTR file 383. The record number in the DPTR file 383 corresponding to the same record number comprises a pointer (e.g. pointer 384) to a manufacturer of that part number. The manufacturer is retrieved by accessing the data in the record in the MFGR file 386 pointed to by the pointer (e.g. pointer 384). The DPTR file 383 record also includes a pointer (e.g. 385) to a record in the XREF file 389. This XREF record may include a pointer back into the DPTR file 383 (e.g. pointer 390) which includes a pointer (e.g. 387) to another record in the MFGR file 386 comprising manufacturer of that part. The process of looking up more records in the MFGR file 386 comprises searching records sequentially in the sorted DPTR file 383 until the HPTR 384 record is not related to the selected part number being considered for inclusion in the list of manufacturers. At this point the part selection device 106 knows all of the manufacturers of the part number entered.

Upon selection of a manufacturer 310, the part selection device 106 will display the particular part information 312 and select a particular part.

FIG. 20 is a flow chart diagramming a procedure for selecting a bearing by an OEM part number and FIG. 23 shows a preferred embodiment file structure containing bearing information stored in data storage device 104 for use in selecting a bearing by part number. Upon selecting the choice of specifying a bearing by OEM part number 586, a user is prompted to enter a part number 588.

Subsequently, part selection device 106 will check if the part number is valid 590. The validity checking is accomplished by finding an HPTR record in the HPTR file 637 which is substantially similar to the part number entered. The HPTR file 637 comprises HPTR records sorted in part number order. Each HPTR record comprises a pointer to a record within an HTAB file 636 comprising a part number. If the part number is not valid, part selection device 106 will prompt the user to enter a part number 588 once again.

Otherwise, if the part number is valid then part selection device 106 will display manufacturers of the part number 592 and prompt the user to select a manufacturer of the part number. The list manufacturers displayed is derived from data storage device 104 by accessing the same record number in the DPTR file 641 as was found to be a valid part number in the validity checking. The DPTR file 641 comprises the same number of records as the HPTR file 637 sorted in the same order by part number. Each DPTR record includes a pointer 640 to a manufacturer in a MFGR file 644 and a pointer 642 to either a CHAIN1 file 646 when the selected part number is an OEM part number or to an XREF file 651 when the selected part number is not an OEM part number. The XREF file 651 is a file sorted by part number comprising records including a pointer 650 into a record within DPTR file 641, a pointer 652 into INFO file 640, a pointer 654 to CHAIN2 file 662 and the price 656 of the part. The CHAIN2 file 662 comprises records including one or more pointers to records within XREF file 651.

For example, a list of manufacturers is derived by taking HPTR record number (e.g. the record including pointer 638) of the valid part number and using it to access the same record number in the DPTR file 641. The record number in the DPTR file 641 corresponding to the same record number comprises a pointer (e.g. pointer 640) to a manufacturer of that part number. The manufacturer is retrieved by accessing the data in the record in the MFGR file 644 pointed to by the pointer (e.g. pointer 640). The DPTR file 641 record also includes a pointer (e.g. pointer 642) to a record in the CHAIN1 file 646. This CHAIN1 file 646 may include one or more pointers to records in the XREF file 651. Each of these records pointed at may include pointers 650 which point back into the DPTR file 641 which includes a pointer (e.g. pointer 640) to a particular record in the MFGR file 644 comprising another manufacturer of that part. The process of looking up more records in the MFGR file 644 comprises searching records sequentially in the sorted DPTR file 641 until the HPTR file record corresponding to the DPTR file 641 record being considered for inclusion in the list of manufacturers is not related to the selected part number. At this point the part selection device 106 knows all of the manufacturers of the part number entered.

Upon selection of a manufacturer 594, the part selection device 106 queries the user whether or not the user wants to enter another parts number 596. If the user wants to enter another parts number, the part selection device 106 will prompt the user to enter a part number 588. Otherwise, part selection means 106 displays the particular part information 598 and selects a particular part. The part information is derived from the data storage device 104 by accessing information pointed to by the records of the DPTR file 641 associated with the part number entered. The specific part information is accessed from the records pointed to in the XREF file 651 and subsequently the record pointed to in the INFO file 640. Upon selection of a particular part 600, part selection device 106 accesses all of the needed bearing information stored in data storage device 104 to select a particular part. Subsequently, the part selection device 106 ends the procedure get part by OEM part number for bearing 602.

Alternatively a user may choose a bearing by part number to OEM part number. FIG. 21 is a flow chart diagramming a procedure for selecting a bearing by a part number and FIG. 23 shows a preferred embodiment file structure containing bearing information stored in data storage device 104 for use in selecting a bearing by part number. Upon selecting the choice of specifying a bearing by part number 604, a user is prompted to enter a part number 606.

Subsequently, part selection device 106 will check if the part number is valid 608. The validity checking is accomplished by finding an HPTR record in the HPTR file 637 which is substantially similar to the part number entered. The HPTR file 637 comprises HPTR records sorted in part number order. Each HPTR record comprises a pointer to a record within an HTAB file 636 comprising a part number. If the part number is not valid, part selection device 106 will prompt the user to enter a part number 606 once again.

Otherwise, if the part number is valid then part selection device 106 will display manufacturers of the part number 610 and prompt the user to select a manufacturer of the part number. The list manufacturers displayed is derived from data storage device 104 by accessing the same record number in the DPTR file 641 as was found to be a valid part number in the validity checking. The DPTR file 641 comprises the same number of records as the HPTR file 637 sorted in the same order by part number. Each DPTR record includes a pointer 640 to a manufacturer in a MFGR file 644 and a pointer 642 to either a CHAIN1 file 646 when the selected part number is an OEM part number or to an XREF file 651 when the selected part number is not an OEM part number. The XREF file 651 is a file sorted by part number comprising records including a pointer 650 into a record within DPTR file 641, a pointer into INFO file 652, a pointer 654 to CHAIN2 file 662 and the price 656 of the part. The CHAIN2 file 662 comprises records including one or more pointers to records within XREF file 651. Another file known as DOUBLE CROSS file 659 is included in the data storage device 104. DOUBLE CROSS file 659 is a file with the same number of records as XREF file 651 sorted by part number comprising records including a pointer 660 into a record within CHAIN3 file 658.

For example, a list of manufacturers is derived by taking HPTR record number (e.g. the record including pointer 638) of the valid part number and using it to access the same record number in the DPTR file 641. The record number in the DPTR file 641 corresponding to the same record number comprises a pointer (e.g. pointer 642) to a record in the XREF file 651. This XREF record corresponds to a record in the DOUBLE CROSS file 659 which includes a pointer 660 to CHAIN3 file 658. The record pointed to in CHAIN3 file 658 includes one or more pointers back into DPTR file 641 each of which subsequently include a pointer (e.g. pointer 640) to a record in the MFGR file 644 comprising an OEM manufacturer of that part number. The process of looking up more records in the MFGR file 644 continues until the last pointer in the pointed at record in the CHAIN3 file 658 does not contain a pointer back into the DPTR file 641. At this point the part selection device 106 knows all of the OEM manufacturers of the part number entered.

Upon selection of a manufacturer 612, the part selection device 106 queries the user whether or not the user wants to enter another parts number 614. If the user wants to enter another parts number, the part selection device 106 will prompt the user to enter a part number 606. Otherwise, the part selection device 106 ends the procedure get part by part number to OEM part number for bearing 616.

Alternatively a user may choose a bearing by a partial OEM part number. FIG. 22 is a flow chart diagramming a procedure for selecting a bearing by a partial OEM part number and FIG. 23 shows a preferred embodiment file structure containing filter information stored in data storage device 104 for use in selecting a bearing by OEM part number. Upon selecting the choice of specifying a bearing by OEM part number 618, a user is prompted to enter a part number 620.

Subsequently, part selection device 106 will check if the part number is valid 622. The validity checking is accomplished by finding an HPTR record in the HPTR file 637 which is substantially similar to the part number entered. The HPTR file 637 comprises HPTR records sorted in part number order. Each HPTR record comprises a pointer to a record within an HTAB file 636 comprising a part number. If the part number is not valid, part selection device 106 will prompt the user to enter a part number 620 once again.

Otherwise, if the part number is valid then part selection device 106 will display manufacturers of the part number 624 and prompt the user to select a manufacturer of the part number. The list manufacturers displayed is derived from data storage device 104 by accessing the same record number in the DPTR file 641 as was found to be a valid part number in the validity checking. The DPTR file 641 comprises the same number of records as the HPTR file 637 sorted in the same order by part number. Each DPTR record includes a pointer 640 to a manufacturer in a MFGR file 644 and a pointer 642 to either a CHAIN1 file 646 when the selected part number is an OEM part number or to an XREF file 651 when the selected part number is not an OEM part number. The XREF file 651 is a file sorted by part number comprising records including a pointer 650 into a record within DPTR file 641, a pointer into INFO file 652, a pointer 654 to CHAIN2 file 662 and the price 656 of the part. The CHAIN2 file 662 comprises records including one or more pointers to records within XREF file 651.

For example, a list of manufacturers is derived by taking HPTR record number (e.g. the record including pointer 638) of the valid part number and using it to access the same record number in the DPTR file 641. The record number in the DPTR file 641 corresponding to the same record number comprises a pointer (e.g. pointer 640) to a manufacturer of that part number. The manufacturer is retrieved by accessing the data in the record in the MFGR file 644 pointed to by the pointer (e.g. pointer 640). The DPTR file 641 record also includes a pointer (e.g. pointer 642) to a record in the CHAIN1 file 646. This CHAIN1 file 646 may include one or more pointers to records in the XREF file 651. Each of these records pointed at may include pointers 650 which point back into the DPTR file 641 which includes a pointer (e.g. pointer 640) to a particular record in the MFGR file 644 comprising another manufacturer of that part. The process of looking up more records in the MFGR file 644 comprises searching records sequentially in the sorted DPTR file 641 until the HPTR file 637 record corresponding to the DPTR file 641 record being considered for inclusion in the list of manufacturers is not related to the selected part number. At this point the part selection device 106 knows all of the manufacturers of the part number entered.

Upon selection of a manufacturer 626, the part selection device 106 queries the user whether or not the user wants to enter another parts number 628. If the user wants to enter another parts number, the part selection device 106 will prompt the user to enter a part number 620. Otherwise, part selection means 106 displays the particular part information 630 and selects a particular part. The part information is derived from the data storage device 104 by accessing information pointed to by the records of the DPTR file 641 associated with the part number entered. The specific part information is accessed from the records pointed to in the XREF file 651 and subsequently the record pointed to in the INFO file 640. Upon selection of a particular part 632, part selection device 106 accesses all of the needed bearing information stored in data storage device 104 to select a particular part. Subsequently, the part selection device 106 ends the procedure get part by partial OEM part number for bearing 634.
